1∶50 000 Geological and Mineral Survey Database of Qixia–Muping Area, Jiaodong Metallogenic Province

The geological and mineral survey in Qixia–Muping area, Jiaodong metallogenic province (also referred to as the survey site) is one of a new round of mineral and geological survey projects initiated by the China Geological Survey. During this project, ten 1∶50 000 mineral geologic maps were mapped (prepared) in accordance with uniform industrial standards and requirements such as the Technical Requirement of 1∶50 000 Solid Mineral Geological Survey (DD 2019–02). Meanwhile, the results of relevant regional geological surveys were adopted, special geological field mapping was conducted by using digital mapping, and indoor mapping (preparation) was combined with outdoor mapping (preparation). Thirty-one ore occurrences (mineralized points) were newly discovered, and 42 prospecting target areas were delineated throughout the area by making full use of the latest results of geological interpretation of 1∶50 000-scale remote sensing data, high-precision ground magnetic survey and gravity survey. Among them, the former consists of 24 gold ore occurrences (mineralized points), four copper ore occurrences and three silver–lead ore occurrences, and the latter is composed of 25 areas of grade A, 14 areas of grade B, and three areas of grade C. All these survey results were included in the database. The geological and mineral survey database of Qixia–Muping Area, Jiaodong Metallogenic Province (also referred to as the Database) integrates the databases of 1∶50 000-scale mineral and geological maps and their map decorations, geophysical databases, remote sensing databases, sample databases, comprehensive result databases, and prospecting engineering databases, with a total data size of 299 MB. It covers the data of 275 mineral occurring sites, and 23 species of polymetallic, precious metallic and non-metallic deposits. The resources of Au, Ag, Cu, Pb, Zn, Mo, W and graphite are predicted to be 836.94 tonnes, 499 tonnes, 727 100 tonnes, 174 100 tonnes, 283 100 tonnes, 357 000 tonnes, 28 000 tonnes and 1.64 million tonnes, respectively. The Database serves as an important reference for basic geological research and exploration of mineral resources in the Qixia–Muping area.
